rLAnT-rnoTEcrIiuG GAP.

To all whom itmuyconcern:

' Be it known that I, WALTER R. SoHIN- DLER, a citizen of the United States, residing at Long Beach, in the county of Los Angeles, State of California, have invented a new and useful Plant-Protecting Cap, of which the following is a specification-.7

My invention relates to devices for covering plants and has more" particular relation to plant protecting caps adapted to be placed over young plants to protect them from the sun or frost or from injurious insects.

The object of the invention is to provide a protecting cap which is preferably formed of semi-opaque material such as will exclude the suns rays and at the same time admit sufiicient light to promote the growth of the plant.

A further object is to provide a cap of circumferential form having anchor means for anchoring the cap in the ground and contoured to provide a substantial strong structure presenting a minimum wind resisting surface so that it will not displaced by wind currents.

Various other objects and advantages will be apparent from the following detailed description of the preferred form. of

embodiment of the invention as illustrated in the accompanying drawings forming a part of this disclosure, and in which Figure 1 is a plan view of the circular blank which is pressed into shape to form my improved cap.

Fig. 2.is a side elevation of the cap.

Fig. Bis an enlaged plan section on line w -w of Fig. 2.

Fig. 4 is a transverse vertical section In the drawin s, 1 designates the circular blank, pre erably of waxed .or oil treated paper, which is pressed to form'the protecting plant cover or cap. The cap is formed with side sections 2-3 and top section 4, the side section 2 extending a relatively short distance upwardly-to a line of fold 5 defining the point of-junction of the section 2 with the adjacent section 3, the walls of the section 2 converging inwardly at a slight angle. The'side section .3 extends upwardly a relatively greater distance to a second line of fold 6 defining the point of junction of said section'3 with the-top section 4, the walls of the section 3 converging inwardly at a relatively greater be easily angle than do the walls of the section 2. I

The top section 4 is of relatively fiat cone formation and the peripheral base edge of the section 2 has a flange '7 turned outwardly to provide an anchor means for anchoring the cap in position, said flange being below the surface. of the ground when cumferential positions nor are they of any definite form or size, their positions and forms depending upon the inherent pecu-.

liarities of each blank and the pressing actioLn'of the dies used in the manufacture of the cap. i

The side sections 23 are each of frustrated-cone formation joined in superposed relation and surmounted by a relatively fiat cone-shaped top section, the cone section 2 having a flanged peripheral base and each section converging inwardly at relatively increased angles.

Specification of Letters Iatent. v Pate ited lVIay 18, 1920. Application filed-October s, 1919. Serial No. 329,309.

The fiat cone-shaped top section and the slanting side-sections provide a substantial and strong structure which is further strengthened by the folds 8, and the entire cap being of stream-line contour presents a minimum wind resisting surface to the action of air currents such as would have a tendency to displace the cap.

In use the cap is placed over a plant with the anchor flange below the surface of the U ground, as-indicated in dotted lines in Fig.

4, and being constructed of semi-opaque material excludes the suns rays while at the same time admits sufiicient light to promotethe growth of the plant. The cap will also effectively protect the plant against injury by frost or. those classes of injurious insects which live'near or above the surface of the ground."

I claim: 1. A plant protecting seamless cap comprising a plurality of superposed frustrated cone-shaped side-wall sections surmounted by a relatively fiat cone-shaped top wall section, the peripheral base edge of the lower wallsection being flanged outwardly.

2. A plant protecting seamless cap comprising a plurality of superposed frustrated cone-shaped side wall sections surmounted by a. relatively flat cone-shaped top wall section, the walls having plaits extending upwardly from the peripheral base edge of the lower section.

3. A plant protecting seamless cap comprising three superposed sections, the base section having'lnwardly converging walls,

and a peripheral base flange, the intermediate section having inwardly converging walls angled to a greater degree than the walls of the base section and the top section being of relatively fiat cone shape.

5. A plant protecting seamless cap formed from a circular blank pressed into shape to provide side walls converging inwardly to a line of fold, then converging inwardly ,at a relatively greater angle to a second line of fold an terminating in a point above said second line of fold to form a a relatively greater angle to a second line of fold and terminating in a point above said second line of fold to form a coneshaped top wall.

Signed at Los Angeles; California, this 1st day of October 1919.
